Title : Methodology for benchmarking MPLS Protection mechanisms
Author(s) : R. Papneja, et al.
Filename : draft-ietf-bmwg-protection-meth-00.txt
Pages : 31

This draft provides the methodology for benchmarking MPLS Protection
mechanisms especially the failover time of local protection (MPLS Fast
Reroute as defined in RFC-4090). The failover to a backup tunnel could
happen at the headend of the primary tunnel or a midpoint and the backup
could offer link or node protection. It becomes vital to benchmark the
failover time for all the cases and combinations. The failover time
could also greatly differ based on the design and implementation and by
factors like the number of prefixes carried by the tunnel, the routing
protocols that installed these prefixes (IGP, BGP...), the number of
primary tunnels affected by the event that caused the failover, number
of primary tunnels the backup protects and type of failure, the physical
media type on which the failover occurs etc. All the required
benchmarking criteria and benchmarking topology required for measuring
failover time of local protection is described Conventions used in this
document

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
